HAIRPIN.

Application filed September 11, 1919.

T 0 all whom it may concern: 7

Be it known that 1, CHARLES It. NALLE, a citizen of the United States, residing at Fort forth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in Hairpins, of which the following is a specification.

This invention relates to new and useful improvements in hair pins.

The object of the invention is to prevent the accidental displacement or the dislodgment of the pin from the hair of the wearer. In carrying out the invention it is proposed to construct the hair pin in such a manner as not to injure the hair of the wearer and to make the pin so that in inserting it in the hair only smooth and continuous surfaces, free from projections and recesses, will be presented; the fastening means being brought into operation after the hair pin is in place.

This invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown, and wherein:

Figure 1 is a View showing the fastening fingers extended,

Fig. 2 is a longitudinal sectional view, the fastening element being withdrawn into the legs of the pin, and

Fig. 8 is a cross sectional detail on the line 3-3 of Fig. 1.

In the drawings the numeral 1 designates a tubular member having the general shape of the ordinary hair pin and made of any suitable material. At its upper end the member 1 has apertures 2 registered with the tubular legs of the member. A yoke shaped operating member 3 is passed through the apertures 2 and is slidable into the legs of the member 1. The member 1 has its free ends open.

Flat spring fingers 4 are attached to the lower ends of the member 3 and extend within the lower ends of the member 1 when the member is withdrawn. By pushing toward the member 1 the fingers 4 are projected and owing to their resilient nature and natural curvature, said fingers curve inward toward each other between the legs of the pin as is shown in Fig. 1. It will be Specification of Letters Patent.

Serial No. 323,145.

seen that with the parts as shown in Fig. 2 the pin may be retained in the hair of the wearer without difficulty as the legs of the member 1 are free from recesses, crimps 0r projections which latter have a tendency to break and injure the hair. By referring to Fig. 1 it will be seen that after the hair pin is in place and the fingers extended, said fingers will act as hooks and retain the hair pin in the hair. By pulling outward on the member 3 and holding the member 1 the fingers are drawn into the legs of the member 1 so that the hair pin may be easily withdrawn from the hair. The fingers 4: must be made of a suitable resilient'material and give a curvature which would cause them to curve toward each other when projected as in Fig. 1.

lVhat I claim, is:

1. A hair pin comprising. a U-shaped tubular member having oppositely arranged legs which are open at their forward ends, said legs having apertures near their rear ends, a yoke-shaped member mounted to slide within the tubular legs, and resilient normally U-shaped fingers secured to the forward ends of the yoke-shaped member in such a manner that said fingers automatically curl into the U-shape when projected forwardly of the open forward ends of the tubular legs, said U-shaped fingers being adapted to be retracted into the tubular legs and to permit of the separation of the U- shaped member and the yoke-shaped member.

2. A hair pin comprising, a U-shaped member having oppositely arranged tubular legs which are open at their forward ends, and provided with apertures at their rear ends, and a yoke-shaped member mounted to slide within the tubular legs and carrying resilient fingers at their for- I ward ends which. are integral therewith, said Patented July 27, 1920.
